Speedometer

[kenarmstrong]

Does anyone know if the speedomoter in the Smart can be recalculated if it is out? I thought mine was out and checked it with two gps units and found I was doing 5 km slower than what the speedomoter was registering. In other words, if my speedomoter said I was doing 50, I was actually doing 45. Has anyone else found similar issues with their speedomoters?

Sounds like you have a built in get out of jail free card/car that makes sure you dont speed. now THATS smart!

Mine was that way too, I put larger tires on (all around) and not it reads exact with GPS and portable radar boards. The odometer also reads off, and I made it worse with larger tires. However both are within the allowable tolerances in that industry.

Mine is about 2 mph optimistic at 60 mph according to Garmin. I've also noticed that the odometer reads a few miles less at each gas stop than the gps. My Subaru's odometer is exactly the opposite, reading more miles than the measurement of my gps.

1.5 miles optimistic and it bugs me.

FWIW, my speedo also reads 2mph less than the Garmin reading.

Automakers face huge fines if there products read slow. Walla they mostly read fast and this makes your life not worth living because _________ .

Also keep in mind your GPS is also only an "estimate"

According to my ScanGauge, My speedo reads about 3 mph faster than I am traveling. The Odometer seems OK tho
